176 THE ENTOMOLOGIST. 



shorter in proportion; they are pale with brown tips, and the 

 base of each is amber-brown ; several minute hairs are dotted 

 over the side, about ten on each segment on either side ; all the 

 hairs are serrated. The spiracles are rather prominent and 

 brown ; behind each spiracle are two pale false spiracles, only 

 slightly darker than the ground colour. The head is very pale 

 greenish yellow, with black eye-spots and brown mouth-parts ; 

 the entire body, including the legs and claspers, is of a pale 

 green, and the whole surface finely cellular. They feed chiefly 

 on the under side of the leaves, and when moulting usually lie 

 along or quite near the midrib. 



Second moult, July 2nd, the second stage also lasting five 

 days. 



Before third moult it measures f in. long, similar to previous 

 stage in general structure excepting several additional hairs, and 

 it is studded with white clubbed processes resembling frosted 

 glass. The colour is a clear light green, with slightly darker 

 green medio-dorsal and lateral longitudinal lines and oblique 

 side stripes. The head is shining pale ochreous-green, eye- 

 apots black, and mouth-parts brown. In this stage they per- 

 forate the leaf, eating large holes all over it. 



Third moult and last, 7th July, the third stage also occupying 

 only five days. 



After third moult, fully grown, it measures from f in. to 

 If in. long. The dorsal surface forms a complete curve from 

 the first to last segment, and has no longitudinal dorsal furrow ; 

 the sides are sloping to the lateral ridge ; the ventral surface is 

 much flattened, overlapping the claspers and legs, completely 

 hiding them ; both the anterior and posterior segments are 

 rounded and projecting, the former quite concealing the head, 

 which is withdrawn into the segment while at rest ; the body is 

 widest at the fifth segment, the head is rather small, shining, 

 and of a very pale ochreous greenish ; eye-spots black, mouth- 

 parts brown ; the segments slightly humped dorsally ; the seg- 

 mental divisions inconspicuously defined. The whole colouring 

 is a clear brilliant green, with slightly darker markings showing 

 in certain lights, of which the oblique side stripes and dorsal 

 lines are the plainest ; the spiracles are outlined with rust- 

 brown. The entire surface is sprinkled with tiny pure white 

 knobs on short stalks, resembling rough frosted glass formed 

 almost exactly like young unexpanded mushrooms ; also short 

 spinous serrated hairs are densely strewn over the whole surface, 

 the longest cover the dorsal and lateral regions, most have the 

 apical half brownish, but many are extremely small and indis- 

 tinct, being wholly green like the body. The surface is finely 

 granulated, of a cellular pattern, the legs and claspers are closely 

 united, being placed almost touching at the base of each pair, 

 occupying a medio-ventral line. They are sluggish in their
